6 Claims. (Cl. 21S-24) This invention relates to a curling iron and has ing portion 6 projects therefrom and is adapted to do particularly with a curling iron advantato fit within the handle, and the extreme end geously electrically heated and designed primaportion as at may he substantially of flat form. rily for use by the individual, although, obviously, The portion 4 may have a raised or bead portion 5 it may be used in shops or the like. 9, an extending portion 10 and an end portion G0 The object of the invention is to provide an ll. These two halves are to be matched together, improved and simplified curling iron structure as illustrated in Fig. 2, with their edges in abutembodying heated elements, and a handle portion ting relation,particularly those edges dening the formanipulatien of the same, assembled together tines and the inner and outer portions of the l in such manner as to provide for quick and easy bight portion as well as the bead portions 5 and 05 attachment one to the other, yet providing a se- 9. The edges of the portions 6 and 10 may fall- Cure connection. A novel feature of the invenaway from each other as shown, and as illustrated tion is the construction of the heated elements at l2 and 13 the metal may fall away rapidly to whichmay and preferably are provided by the flat portions 7 and 11. The two halves may matched halves suitably united to form a hollow now be united as by means of securing the abutinterior, and such matched halves may be conting edges, one to the other, by welding or by .structed of metal stampings, die castings, or the molten sealing metal preferably vof fusing point like. The securing means between the heated high enough to withstand the heat to which the section and the handle may be constituted at iron is subjectedin use. Such molten sealing least in part by integral portions of the heated metal may be copper. The manner in which two parts, or onintegral portions or extensions theremetallic parts may be welded together under a of which are disposed within the handle. reducing or non-oxidizing environment is known The invention also aims to provide a curling to those skilled in the art and need not be gone iron embodying preferably two heating elements further into.

of prong or tine form, and these are given dimen- 1t should be pointed out, however, that before 8@ sions and so spaced with respect to each other to the two matched halves are secured together the produce a wave of desired `and lasting quality. heating elements may be located therein, such In thc'accompanying drawing: heating elements being shown at 14 and 15 and Fig. l is a' sectional view taken through the may be carried by a supporting block 16 disposed curling iron constructed in accordance with the in the bight portion and through which electrical invention showing the structural features conductors 17 extend. It is within the invention thereof. to so shape the heated elements that the matched Fig. 2 is a view taken at right angles to Fig. 1 halves may first be united and then the heating illustrating the handle in cross section and showelements located. ing a heated element in side elevation. The handle is shown at 20, and it is hollow and 9G Fig. 3 is a sectional view taken substantially on preferably designed to be slipped over the spaced line 3 3 of Fig. 2. ends of the matched halves, and it may be pro- Fig. 4 is a sectional view taken through a heatvided with an insulating washer 2l. The conu ed element on line 4 4 of Fig. 1. ductors 17 extend through the hollow handle, and Fig. 5 is a detail in plan of a securing device. the hollow formation may be enlarged at one end, 90

The curling elements proper, or the heated as shown at 22, thus to form a shoulder 23. For elements, as they may be termed, may comprise a uniting the handle to the heated elements the pair of spaced prongs l and 2. They may be conmaterial of the heated elements may be formed structed by two matching halves, one of the with integral struck-out lips 24, and a washer 25 45 matching halves may consist of an integral piece may be slipped into the handle and forced over of metal, say a stamping, fashioned to provide the lips 24 against the seat 23. The lips 24 spring a prong half for the leg 1 substantially semi-ciroutwardly in this action and engage over the cular in cross section, and a similar hollow or washer. The Washer as shown in Fig. 5 may have semi-circular in crosssection portion for the leg internal hat portions 26 for location underneath Cil bight portion,`as at 3, and this matched half, as A suitable switch body such as a snap switch shown in Fig. 2, is identied by the character 4. now available upon the market, may be inserted The other matched half is shown by the charbetween the flat portions 7 and 11. The switch acter 5. The half 5 may be provided with a probody is shown at 30 into which conductors 31 jecting or bead like 'formation 8, and an extendlead, and the switch body may have insulation suitable washer 38 may t` material 32 on each side thereof for fitting over the flat portions 7 and ll, as illustrated in Fig. 3. The interior structure of the switch need not be gone into; suiiice to say, the .switch may carry an arm 35 having a ball portion 36 located in a socket arranged to snap over from one side to the other for making breaking the circuit. This arm may be carried by the switch prior to its insertion into the handle, and by disposing the switch at an appropriate it may be inserted into the C-nlauged hollow poi on 22 until the arrn 35 is so located that it nia se caused to projec out through an aperture i7 in the handle. A en be screw threaded onto the portion of the switf l soclreting the handle for tightly engaging the andle on one side while a washer or the like SS engages it on the inside.

A closure disk may now be located and the same is shown at 40, and it advantageously is in the form of a piece of rubber apertured for the passage therethrough of the electrical conductor and having an annular rib el for seating into an annular Titel-nal groove 42 in the handle. The closure disk 4.0 is prefeably sufficiently iiexible to permit it to be compressed for location whereupon the saine expands so that the rib 4l seats in the internal channel.

In using the curling iron a strand of hair may be taken and wrapped over the prongs in gure eight fashion. This gives a rather desirable flat Wave. The end of the strand may then advantageously be wrapped around one prong; this gives the end of the strand a rather round wave.
